I think he would be done by 96. loses against holyfield in 1992 Then he loses against Bowe again if he gets a shot or loses to Holyfield in rematch. He is considered Hypejob. And can not earn as much money after that loses. He could fight Foreman and Morrison for money fights and i am not sure he defeats Foreman 100% not the version Holyfield beat anyway. If he gets shot at Moorer as HW champ he kos him like George did and becomes champ, He avoids Lennox. its hard to predict i think after loses to Holyfield and or Bowe he is done as serious contender also that fights would have made him decline faster. I was thinking what if David Tua fought in Tysons era and who would have stoped him?
Not sure if he would have been motivated by the late 1990s as he would have made a LOT of money then still. Although, I think he may have lost to Holyfield in 1991.
